LEATHER-FINISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 561,465, dated June 2,1896. Application filed December 18.1895. serinivo. 572,548. (No model.)

To aZZ whom it may concern:

Be it known that 1, JONATHAN WoRsDnLL, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Leather-FinishingMachines, of which the following is a specification.

The object of my said invention is to produce a machine whereby strapsof leathersuch, for instance, as are used in making harness-maybeblacked and finished ready for use.

A machine embodying my said invention will be first fully described, andthe novel features thereof then pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof,and on which similar letters and figures of reference indicate similarparts, Figure 1 is a side elevation of a machine embodying my saidinvention; Fig. 2, an end elevation of one end thereof; Fig. 3, anelevation of the other end thereof; Figs. 4c, 5, 6, 7, 8, and 9,transverse sectional views, on an enlarged scale, on the dotted lines 44:, 5 5, 6 6, '7 7, 8 8, and 9 9, respectively, in Fig. 1 andillustrating the construction in detail at said various points; Fig. 10,a horizontal sectional view looking downwardly from the dotted line 1010, and Fig. 11 a detail sectional view illustrating the method ofsecuring the main-shaft pulleys to the main shaft of the machine.

In said drawings the portions marked A represent the framework of themachine; B, the main shaft thereof; O, the blacking-brush shaft; D, theblacking receptacle; E, the blacking-tank; F, the side finishing orburnishing roll shaft; G' and G, the edge finishing or burnishin g rollshafts, and H guides to the edge finishing or burnishing rolls.

The frame A is of suitable construction for the purpose, consistinggenerally of legs and a top or table, and contains bearings for themechanism and other parts of the machine. This frame and table is,generally speaking, of a simple construction and will not be furtherdescribed herein, except as to special features, or incidentally indescribing the other portions of the machine.

erated independently.

The shaft B is mounted in hearings in the frame A, preferably at thelower part,'and may be driven either by a belt running to a pulley B orby a hand-crank, as shown by dotted lines at X in Fig. 1, connected,either directly or through gears 1 2, to said main shaft. Said shaftbears the pulleys 3, 4-, and 5, from which the blacking-roll and thevarious finishing or burnishing rolls are driven by means of belts B Band B, as will be presently more fully described. As shown most plainlyin Fig. 11, these pulleys are mounted loosely upon the shaft and runbetween collars l) b thereon, the latter of which collars are providedwith pins 19, which pass through them parallel with the shaft and areadapted to enter perforations in the hubs of the pulleys, as shown,whereby said pulleys and said collars are locked together, so that thepulleys may be revolved by the shaft through the medium thereof. This isso that the several rolls of the machine may be op- Each pin 13 isnormally held into engagement with the corresponding pulley by a spring.9, inclosed within a suitable socket in its collar 1), as shown in saidFig. 11. A smaller pin 19 extends in from the head of thepin p andparallel there with, and is adapted to register with and enter aperforation in the collar Z) or to be turned so as not to enter saidperforation. When itis desired that the pulley shall run loosely, thepin 19 is withdrawn from engagement with the hub and revolved somewhatin its bearing, so that the end of the pin 1) will rest against thesurface of the collar 1), instead of entering the perforation therein,as will be readily understood.

The blacking-brush shaft 0 rests in bearings in hangers A, carried bythe top or table of the frame A, and carries a rotary brush, as shownmost plainly in Fig. 5, which is adapted to come in contact with oneside of the piece of leather L being treated. The leather is held intoforcible but yielding contact with said brush by an opposing roller 0,mounted in bearings O carried on rods G which rods pass down throughperforations in the table-like top of the frame A, and are connected attheir lower ends with a pivoted lever-like frame 0, which is normallyheld down by a spring S, but is adapted to be raised by a treadle Tthrough a rod R. The tension of the spring S is governed by a screwtension-rod 6,having a thumb-nut 7. The pressure of the roll 0 on thepiece of leather L may thus be regulated as desired, and the roll may beraised out of contact whenever desired by means of the treadle T. Asindicated most plainly in Fig. 5 by means of arrows, the leather is bypreference drawn against the motion of the roll and brush, so that theblacking is thoroughly brushed into the fiber of the leather. One orboth sides of the leather may be treated in this manner, as may bedesired, said leather before treat ment having preferably been cut intothe sized strips in which it is to be used. The opening in the tablethrough which the upper surface of the brush projects against theleather may be regulated,as desired, by means of the adjustable platesI, which form the surface with which the leather immediately comes incontact, and which themselves are secured, by means of the screwspassing through slots therein, upon a trough-like plate P, mounted onthe top of the frame I.

The blacking-receptacle D containing the blaeking is secured to theunder side of the frame-top, and is rendered removable by means ofdetachable hangers. It is provided with projections d on its under sidesnear its upper edge, one of which rests on a ledge a and the other ofwhich rests on a revoluble button or catch a, as shown most plainly inFig. 5. Turning said button or catch permits said blaeking-receptacle tobe withdrawn from place, as will be readily understood.

The tank E is adapted to contain a supply of blacking, and is mounted011 a pipe E, which leads to the receptacle D. This is provided with avalve 6, whereby the supply of blacking may be shut off or permitted toflow, as may be desired, it being desirable to have only a sufficientquantity of blacking' in the receptacle, so that the lower edge of therotary brush will just enter it.

After the blacking has been applied to the leather, it is first wipedand then greased, and afterward passed between the finishing orburnishing rolls F F the former of which is carried by the shaft F, saidshaft being mounted in stationary hangers A carried by the top of theframe A. The roll F is carried in movable bearings F mounted 011 rods F,the lower ends of which engage with a pivoted frame F, and which isnormally held down by a spring S, but is adapted to be raised by atreadle T, operating through a rod R in a similar manner as in the caseof the blacking-brush and its opposing roll. As shown most plainly inFig. 7, these rolls F and F are preferably covered by canvas, which Ihave found. to be the best material for thoroughly rubbing andburnishing the leather, and, as before, the leather is pulled throughthem oppositely to the direction of motion of their surfaces where theycome in contact therewith.

The shafts G and G carry rolls adapted to finish or burn ish the edgesof the leather straps in the same way that the rolls F and F finish orburnish the sides thereof. As the straps are of various thicknesses, andas it is desired to give them different shapes, a machine,in order to beeifective,must necessarily have a number of contact-surfaces; otherwisea great number of machines will be required to do the work. As shown inFigs. 1 and 10, these rolls G and G have a considerable number ofgrooves, varying in size and shape, the variations in size being toaccommodate the different thicknesses in leather and the variations inshape for the purpose of producing the varied form of edge. Theroll-shaft G is mounted in stationary bearings carried by the top of theframe A. The shaft G is carried in movable bearings G, mounted in slidesor ways W, said slides or ways being mounted on said frame-top. Thisarrangement permits the treatment of straps of varying widths as well asof varying thicknesses. As shown most plainlyin Fig. 2,and also by meansof dotted lines in Fig. 8, the belt 13, by which these rolls are driven,run over two small pulleys 8 and 9, mounted on stud-shafts on theslidable bearing, which also carries the roll-shaft G. As will bereadily understood upon an inspection of said Fig. 2, the bearingstructure G can be moved vertically without varying the tension of thebelt. Said bearing structure is connected to rods G which pass downthrough perforations in the frame-top and connect with a pivoted frameG, which is normally held downwardly by a spring S, but is adapted to beforced up by a treadle T through a rod R This mechanism is similar tothe other two corresponding treadle mechanisms of the machine, exceptthat in this case I have used a different form of spring.

Each of the frames 0 F and G consists, essentially, of a rod or shaftand two arms connected rigidly thereto, said rods or shafts beingmounted in hangers depending from the under side of the table-like topof the frame of the machine. In each case the outer ends of the arms areslotted somewhat, and into these slots enter pins secured at the properpoint on the rods 0 F, and G The guides II are secured to the sides ofthe slideways W, an d the perforations therein correspond to the groovesin the face of the rolls. Said perforations are in the form of verticalslots of considerable length, so that the varying widths of the strapsmay be accommodated without shifting said guides.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a leather-finishing machine, the combination, of a framesupporting the table and operating mechanism, a blacking-receptaclesecured below said table under an aperture therein, adjustable plates bywhich the width of said aperture may be increased or diminished, arotary blacking-brush mounted in said receptacle with its top in saidaperture, an opposing roll mounted in bearings carried by a swingingframe and arranged to hold the leather into contact with said brush, aspring arranged to normally hold said roll toward said brush, and atreadle whereby it may be forced away therefrom, substantially as setforth.

2. In a leather-finishing machine, the com bination, of the operatingmechanism, and a pair of edge-finishing rolls arranged opposite eachother and mounted to be adjusted to greater or less distances from eachother, each of said rolls being formed with a series of circumferentialgrooves of varying widths and forms, those in one corresponding to thosein the other with which they are designed to 00- act, and means forsupporting the straps in edgewise position between said rolls,substantially as set forth.

3. The combination, in a leathcr'finishing machine, of a pair of edgefinishing or bur nishin g rolls, one of said rolls being mounted instationary bearings, and the other in bearin gs in a sliding or movablebearing structure, stud-shafts also carried by said sliding or movablebearing structure with pulleys thereon, whereby said movable bearingstructure may be moved toward or from the stationary bearing structureWithout varying the tension of the belt, substantially as shown anddescribed.

4. The combination, in a leather-finishing machine, of a pair ofedge-finishing rolls containing numerous grooves of varying sizes andforms, means whereby said rolls may be adjusted toward or from eachother, and guides secured in front of said rolls having vertical slotsof widths corresponding to the grooves in the rolls, and of a length notless than the extreme adjustment of said rolls, substantially as shownand described.

In witness whereof I have hereunto set my hand and. seal, at New Yorkcity, New York, this 13th day of December, A. D. 1895.
